Abstract: A method of cloning models of a physical fastener may include a computer-aided design (CAD) system receiving one or more instructions that identify a base model of a physical fastener. For each of one or more socket models having at least one characteristic corresponding to the base model, the method may further include generating a clone fastener model based on the base model of a physical fastener and at least one physical property of the one or more socket models.

Abstract: A computer-implemented method and system automatically detects stress singularity in a three-dimensional (3D) computer-aided design (CAD) model. A potential area of high stress is detected. A finite element mesh of the 3D CAD model is refined, at least in the potential area of high stress, after which, whether the high stress value converges is determined. A user is alerted that the potential area of high stress is an area having one or more elements of stress singularity. Suggestions are made regarding how to eliminate the stress singularity and the user is enabled to modify the design of the 3D CAD model to eliminate the stress singularity.

Abstract: A method of executing a simulation model while generating an associated structural model includes changing, by a computer-aided design (CAD) system, the structural model. The method further includes evaluating, by the CAD system, at least one trigger criterion to determine if the change to the structural model is a simulation trigger event. The method also includes executing, by the CAD system, the simulation model if the change to the structural model is determined to be the simulation trigger event.

Abstract: A method for designing a mechanism including rigid bodies and mechanical joints including obtaining input parameter values which represent the mechanism in an input state. The method also includes determining output parameter values which represent the mechanism in an output state. The determining includes minimizing an objective function under constraints. The objective function penalizes a distance between the output dimensional values and the input dimensional values. The constraints include a first constraint representing verification of the closure equation by the output parameter values. The constraints further include a second constraint representing mobility of the mechanism in the output state. This forms an improved solution for designing a mechanism comprising rigid bodies and mechanical joints.

Abstract: A system and method for accessing a remotely located two dimensional (2D) drawing via a mobile device at a work site includes a reference device at the work site configured to provide a geographical reference to the mobile device. A document retrieval system is configured to access the plurality of 2D drawings in a document repository. The mobile device provides an annotated document to the document retrieval system. The document retrieval system accesses the 2D drawing in the document repository based on the annotated document, and provides a rasterized version of the 2D drawing to the mobile device.

Abstract: Embodiments perform automatic slot propagation in CAD models. One such embodiment identifies a first instance of a tab feature in a CAD model. The first instance of the tab feature is associated with a corresponding first instance of a slot feature. Next, a second instance of the tab feature in the CAD model is identified, e.g., a tab that does not have a slot. In turn, the slot feature is automatically propagated by creating a second instance of the slot feature in a component of the CAD model. The second instance of the slot feature corresponds to the identified second instance of the tab feature. In this way, embodiments automatically create slots for tabs without slots.

Abstract: Embodiments are directed to functionality for automatically trimming structural members in computer-aided design (CAD) models. An embodiment obtains a CAD model that includes a joint where a first structural member and a second structural member meet at an extremity of at least one of the first structural member and the second structural member. In turn, trimming is automatically applied to the joint using one or more processor executed rules. The one or more rules indicate the applied trimming based upon (i) geometry of the first structural member, (ii) geometry of the second structural member, and (iii) location of the joint where the first structural member and the second structural member meet.

Abstract: A method configures a housing for an assembly via a simulation of the assembly and housing in a computer assisted drafting environment. The assembly includes compartments for components and at least one opening between two neighboring compartments. Based on received parameters, aspects of the assembly and the housing are defined, bounding volumes are created for each housing compartment, and bridgings between compartments are defined. A base shell volume of the housing is calculated using Boolean operations on the bounding volumes, and a topological volume is calculated from the base shell volume. A housing assembly model is determined based on the topological volume.

Abstract: A pseudo micro computed tomography (CT-like) image of a porous material is produced. A chemistry-based 3D structure of a porous material system is generated, and a Connolly surface for the 3D structure is determined. A volume field of the 3D chemistry-based structure is calculated from the Connolly surface. A text-format file layer having layer by layer information of the volume field is generated. The text-format layer file is converted into a CT-like binary image file in the RAW format. The binary image file is converted to a black and white or grayscale images. A pore size analysis (PSA) simulation is performed to produce grain images and pore images for the porous material system.
